To all whom it may concern Be it known that l, llnnnr M. Senna, acitizen of the United States, residing at Quincy, in the county of Adamsand State of Illinois, have invented certain new and useful Improvementsin Heating Systems for Breeders, Incubators, and the like, of which thefollowing is a specification.

My invention relates to an improvement in heating systems for breeders,incubators, and the like, the present invention being ot the nature of,but an improvement on, the invention set forth in m applications Ser.Nos. 451388, filed in the atent Oce March 10, 1921, and 467722, and May7, 1921.

What ll want to cover in this present application is a combination bywhich the oil level carried in the float, and the oil level carried by te bottle are so nearly coincident the the burner cannot flood oroverflow in the event of the float mechanism getting out of order.

In my previous constructions, and also in every float constructionhitherto patented, the oil level as determined by the bottle is alwaysconsiderahly higher than the overflow point of the burner, so that, incase the float valve should fail to function, the oil would flood theburner, unless an overtlow was revided at the float chamber.

In the shove-mentioned applications, there is a vent hole in the floatchamber, which: also serves as an overflow in case the float valveshould fail to shut ed the oil. The vent hole referred to, is absolutelynecessary, for if the float chamber is not vented, the air could notescape, hence the oil would never rise far enough to close the floatvalve. The vent, therefore, serves a double purpose, but what I haveaccomplished in the resent invention is the prevention of allpossibility of the oil overflowing at any point.

The construction, and arrangement of the float, balls-valve, etc., aresubstantially the same as in my previous applications, but the openingin the center of the float is en j'nrge for the reasons that will appearhereinafter.

The accompang drawing is a vertical sectional view.

A, is the usual oil bottle; B, is the metal oil chamber; 0, is adiaphragm dividing the oil ch: into upper and lower come .10. l), is avent for the lower coinpertment; E1, is a -i metal cup to re ceive theneck of the oil bottle A. This cup extends through an openin 1 formedtherefor in the center of the diaphragm. The cup has a cramped u goeredge 2, which rests removably upon the iaphragm.

F, indicates a fine screen or strainer located within the cup; and G, isa hemeplate upon which the strainer is supported. This loafie-platerests centrally on the bot tom of the cup, and has the function ofpressing back the bottle-valve 3 to permit the oil to escape from thebottle. f

l-l, represents the float; l, a plate coverin the opening 5 in thecenter of the float, this plate being provided with holes 6 to permitthe oil to pass free]. therethrough.

J, is the ball-valve, whic may either be fastened to the plate I orpermitted to rest in valve-seat 4 as illustrated in the drawing.

The seat 1 for the ball J in the bottom of the cup E may be pressed inthe sheet-metal, Every economy in space must be taken care of in orderto bring the neck of the bottle as near as possible to the oil levelcarried by the float, as indicated by the line L. The oil level ascarried b the bottle is indicated by the line K just s ightly above.

In operation, the depth of oil in the bottom of the oil groove of theburner 8 is hardly one-sixteenth of an inch when carrying full volume.The depth oil the oil groove'of the burner is usually five-eighths, inmost types of burners, the oil groove is considerably deeper than this.

In view of the oil groove in the burner, and the depth of the oil at theoperating point, it will be clearly seen that the Oll could not overflowatthe burner even if the lloat failed to function. While the heater isin operation, the burner of course will take care at any slight leakageof oil at the ball-valve, or in other words, the burner will always usemore oil than could possibly leak past the ball-valve, providing it isnot prevented from seating. This slight leakage, however, would incourse of time flood the burner or cause the oil to overflow at someother point after the flame is extinguished.

Such a condition is more or less ebjece tienable. With my presentconstruction, the chamber or cup E receivin the oil from the bottle isdrawn out of a single piece, hence there is no possibility of a lea atthe valve seat 4 of the ball valve J.

The gauze scr en 1 Will prevent any til til

Mid

age except 1M9 coarse dirt from getting into the ball-valve, and as thecup E can be lifted out, it afiords every opportunity to keep theseparts perfectly clean. Since the oil level is within the cup E, thediaphragm need not be soldered tight in the oil-chamber C, in factarrangement can be provided by -means of which the diaphragm C could belifted out, and the entire float removed. Ordinarily there is nooccasion for this, however, since the only parts that will ever needattention are the screen F, and the valve-seat 4 for the ball valve J. I

The baflle-plate G is for the 1purpose of supporting the screen F, and aso for the urpose of supporting the bottle-yalve 3. Men this valve isopen, the o1l flow; through the screen F, through opemngs 9 in theheme-plate.

The entire structure may be raised and lowered through the screw 10 andthe nut 11, and locked with a key 12.

The manner of applying thls new construction to the balance of theheater may be the same as in my other application.

I claim: r

1. The combination with an oil supply and a comparatively shallow oilcham forming a seat for the'support thereof, of a float in the oilchamber approximately on a level with the outlet from the oil supply,whereby the oil level carried by thefloat and oil supply chambers areapproximately coincident.

2. The combination with an oil sup ly and a comparatively shallow oilchamber formin a seat for the support thereof, of a float 1n the oilchamber approximately on a level with the outlet from the oil sup ly,whereby the oil level carried by the dim and oil supply chambers areapproximately coincident, and a ball valve carried by the float forcontrolling the passage of oil from the oil supply to the oil chamber.

3. The combination with an oil .sup ly chamber, anoil =chamber having a5a phragm t ereacross, whereby it is divided into two compartmentshaving an opening b therethrough, a cup extending down through saidopening, and receiving therein the outlet of the oil sup ly, and havinga valve seat therein, of a cat approximately in the plane of the outletfrom the oil supply, the float carryin a valve for controlling thevalve-seat out 8t Of $11? p 7 removably resting upon mantra hThecombination with an oil supfilmy whereby it is divided oat approximatelyin the into two. compartments having an opening therethrough, a cupextendingldown throng said opening, and receiving t crew the outlet ofthe oil sup ly and having a valveseat therein, of a oat approximately inthe plane of the outlet float carrying a valve for controlling thevalve-seat outlet of the from the oil supply, the
